Spontaneous imbibition using surfactant has become an effective method for enhanced oil
recovery (EOR) in tight reservoirs. In order to guide EOR in the oilfield, it is of great …

Unconventional reservoirs, such as compact reservoirs, have been extensively developed.
The Changqing Oilfield is currently the largest compact reservoir oilfield in China. An …

Micro/nanoparticles have emerged as pivotal agents in enhancing oil recovery (EOR),
offering novel approaches to optimize the extraction processes in complex reservoirs. This …

Spontaneous imbibition is an important mechanism for developing fossil hydrogen energy.
However, the research of imbibition micromechanisms and scaling methods in tight …

This paper presents a generalized mathematical model that comprehensively characterizes
the flow behavior of matrix nanopores and natural/hydraulic fractures in tight oil reservoirs …

In the process of the large-scale hydraulic fracturing development in oil and gas fields,
reservoir damage caused by polymer fracturing fluid is inevitable. The real oil and gas field …

Spontaneous imbibition has an important influence on the well production and water cut in
shale oil development, but the imbibition mechanism in the pore structure and the influence …

Spontaneous imbibition is an essential method to enhance recovery during fracturing shut-in
of tight reservoirs. However, most of the investigations are primarily focused on the …

Slickwater fracturing fluids have gained widespread application in the development of tight
oil reservoirs. After the fracturing process, the active components present in slickwater can …

This study aims to investigate the mechanism behind surfactant enhanced oil recovery
under reservoir conditions through experiments on spontaneous imbibition with surfactants …
